To the vertical portion of the bracket 25 a vertical recessed slide 2? is secured by a horizontal clamping screw 28 working in. a slot in the bracket 25.

The, recessed slide 2? hasa horizontal portion through which a vertical adjusting screw 29 is threaded with its lower end'abutting against thetop of the bracket 25. By manipulating adjustsurface of the soleis held fiat across the roll,

the flange on the roll 36, the reduced edge is bent downwardly'so that the bottom of the sole; 'is presentedflat across the feed roll ing nuts 3t and 255 on the screw 29, the vertical position of the slide 2'! may beregulated. A

A screw 3% holds the block .32 in position against the actionof a compression spring embracing the shank of the screw 3%, said spring tending always to rock the block outwarddown and then. the slide 21 is clamped in adjusted position. A sole is then pushed in between .the rolls l9 and 36 so that the operator may see how the roll 36 pres'ses the sole against the roll it. By turning the screw 34 the angle of the axis of the roll 36 is varied until the under l9. The inner flange of the roll 3% bears on the inner margin of the sole to prevent it from tilting.

Thus; the machine may be adjusted for a light womans sole and need no changes unless the work varies so that much cement-carrying feed roll disposed partially with-,

heavier solesare to be treated,

c Having thus described my invention what I,

claim as new and desire to secure by Letters Patent is:

1. A machine for cementing the rnargins of soles, which comprises a cement reservoir, a

portion of their shanks. With this arrangement in said reservoir, andangle bracket, bolts secur ing the bracket to the top of the reservoir, springs about said bolts foryieldingly securing the bracket to the top off said reservoir, a vertically adjustable slide secured to said angle bracket, a block pivotally mounted on said slide, a spring disposed between the block and the slide and tending to rock the upper end of said block outwardly from the slide, and a presser roll rotatably mounted on said block.

' 2. A machine for cementing the margins of soles, which comprises a reservoir, a knurledcement-carrying.feedroll, an angle bracket disposed on said reservoir adjacent said feed roll,

boltssecuringthe bracket to the reservoir, springs about said bolts permitting yielding movement of said bracket to and from said feed roll, a presser roll disposed above said feed roll, a vertically adjustable slide, connected to said bracket, a block carrying said presser roll and pivotally secured to said slide, and a spring urging said blockand presser roll away from said slide.

3, A machine for cementing the margins of soles, which-comprises, a reservoir, a cement carrying feed roll, an angle bracket secured on said reservoir adjacent said feed roll, a springdispcsed beneath said bracket and providing a-ylelding mounting for said angle bracket, a block pivotally secured to said bracket, a presser roll carried by said block, and a spring disposedbetween the block and the bracket and tending to .iorce said block and presser roll down and away from said bracket, whereby a slight increase in the thickness of a sole passing between the feed roll and the presser roll will be compensated for by yielding of the presser roll and block with respect to the bracket, and a major increase in the thickness of a sole will be also compensated for by movement of the bracket on its mounting.

4. A sole cementing machine comprising a cement reservoir, a cement-carrying feed roll keyed on a shaft journaled in said' reservoir, a hinged cover having anaperture for said feed roll, a bracket having an upstanding portion, bolts securing said bracket to the cover, a plurality of springs disposed around the bolts to provide a yielding mount for said bracket, a verticallyad-
